An access panel is primarily made by Bending. Sheet-metal bending (press braking) forms a straight bend in sheet by pressing it into a V-die, building a 3D part from flat stock through a sequence of bends. Below is the full route to make an access panel, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How an access panel is made
The usual route, raw material to finished part. The amber step is where the access panel gets its basic shape.
Material
Select the sheet grade and gauge for the access panel.
Blanking
Cut the flat blank, by laser for low volume or a blanking die at scale.
Tooling Low (laser) to high (die) Tolerance ±0.05 to 0.3mm Lead days to weeks
Bending
Form the blank into the access panel on the press brake.
Tooling Low Tolerance ±0.1 to 0.5mm / ±0.5° Lead 1 to 3 weeks
Secondary features
Punch or drill the holes and cut-outs the part needs.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Joining
Spot weld, fasten or bond into the assembly where the access panel is more than one piece.
Tooling Medium Tolerance joint Lead immediate
Finish
Deburr the edges and powder coat or plate for protection and colour.
Tooling Low Tolerance adds 0.05 to 0.2mm Lead days
Inspection
Check formed dimensions, hole positions and flatness.

General pointers. The full design-for-manufacturing list for an access panel is in the dossier.
Bend radius too tight.Use >=1x thickness inside radius.
Flange shorter than brake minimum.Lengthen the flange.
Cost
What an access panel should cost
Press-brake forming; cost scales with number of bends and setups. Few bends, generous tolerance = cheap.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for an access panel at your volume, in your currency, are in the dossier.

What does an access panel cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $9.7 to 27 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is an access panel made from?
Common choices are Mild steel; Aluminium 5052; Stainless 304.
What is the main process for an access panel?
Bending. Enclosures, brackets, panels and chassis in low to high volume.
